I'm using Mockjax for the first time to mock a Restful API which will return a series of data given an id. Right now i have a json file that has several Items, and i would like to have a function inside Mockjax (or where necessary) to return only the queried ID. how can I achieve this?
current code :
$.mockjax({
url: "/Api/Cases/{caseId}",
proxy: "/mocks/cases nuevo.json",
dataType: 'json',
responseTime: [500, 800]
});
$.ajax({
type: 'GET',
url: '/Api/Cases/',
data: {caseId: taskId},
success: function(data){
//use the returned
console.log(data);
}
});
current error:
GET http://localhost:8080/Api/Cases/?caseId=100 404 (Not Found)
Great question... yes, you can do this. But you'll have to write the functionality yourself using the response
callback function and then making a "real" Ajax request for the file (instead of using the proxy
option). Below I just make another $.ajax()
call and since I have no mock handler setup for that endpoint, Mockjax lets it go through.
Note that setting up URL params is a little different than you suggest, here is what the mock setup looks like:
$.mockjax({
url: /\/Api\/Cases\/(\d+)/, // notice the regex here to allow for any ID
urlParams: ['caseID'], // This defines the first matching group as "caseID"
responseTime: [500, 800],
response: function(settings, mockDone) {
// hold onto the mock response object
var respObj = this;
// get the mock data file
$.ajax({
url: 'mocks/test-data.json',
success: function(data) {
respObj.status = 200;
// We can now use "caseID" off of the mock settings.urlParams object
respObj.responseText = data[settings.urlParams.caseID];
mockDone();
},
error: function() {
respObj.status = 500;
respObj.responseText = 'Error retrieving mock data';
mockDone();
}
});
}
});
There is one other problem with your code however, your Ajax call does not add the ID to the URL, it adds it to the query string. If you want to use that API endpoint you'll need to change your source code $.ajax()
call as well. Here is the new Ajax call:
$.ajax({
type: 'GET',
url: '/Api/Cases/' + taskId, // this will add the ID to the URL
// data: {caseId: taskId}, // this adds the data to the query string
success: function(data){
//use the returned
console.log(data);
}
});
Note that this presumes the mock data is something like:
{
"13": { "name": "Jordan", "level": 21, "id": 13 },
"27": { "name": "Random Guy", "level": 20, "id": 27 }
}
What I have ended up doing, is: I have left the $.mockjax
function untouched, and i have manipulated the data inside the ajax request, using jquery's $.grep
function as follows:
$.ajax({
type: 'GET',
url: '/Api/Cases/' + taskId,
success: function(data){
//note you have to parse the data as it is received as string
data = JSON.parse(data);
var result = $.grep(data, function(e){ return e.caseId == taskId; });
//since i'm expecting only one result, i pull out the result on the 0 index position
requestedData = result[0];
}
});
The $.grep()
method removes items from an array as necessary so that all remaining items pass a provided test see Jquery API , And since our test is that the caseId attribute of the element equals to the taksId variable sent, it will return all the elements that match the given Id, in this case, only one, this is why I've taken only the result on the 0 index position requestedData = result[0];
**Note: ** A more suited solution would be a mixture between what i've done and @jakerella 's answer, since their method implements the find element method inside the mockjacx function, and my function presumes a usual JSON response:
[{"caseId": 30,"name": "Michael"},{"caseId": 31,"name": "Sara"}]
